The Yellowstone Supervolcano also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake [86] 174,000 years ago. Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone caldera since the last supereruption.
The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey ...
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
A new study published in Nature suggested that Yellowstone’s magma and other superheated components have “shifted” northeast of the park’s sprawling caldera — a gigantic volcanic crater ...
The Yellowstone Caldera has two resurgent domes formed by magma upwelling called Sour Creek and Mallard Lakes. [8] The magma chambers under the Yellowstone Caldera provides heat and energy for large hydrothermal systems. [8] [9] The Yellowstone Caldera has the greatest concentration of hydrothermal features in the world, and is an active system ...
Yellowstone Caldera—Lava Creek Tuff: 0.639: Yellowstone hotspot: 1,000 Last large eruption in the Yellowstone National Park area estimated energy yield 875,000 megatons of tnt [39] [9] [10] Awasa Caldera: 1.09 Main Ethiopian Rift: 1,000 [40] Cerro Galán: 2.2 Catamarca Province, Argentina 1,000 Elliptical caldera is ~35 km wide [41]
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions.

The supervolcano feeds the world’s largest group of hydrothermal features, which are a wonder to behold. ... The most recent volcanic eruption occurred in Yellowstone approximately 650,000 years ...
